MediaTek Dimensity 8450
The MediaTek Dimensity 8450 is an ARM-based SoC (system-on-a-chip) for smartphones that is manufactured using the 4 nm process. In terms of performance, the processor is in the upper class and supports all current mobile communications standards including 5G SA. Compared to the older Mediatek Dimensity 8400, the 8450 offers the same specifications.
The MediaTek Dimensity 8450 works with eight ARM Cortex-A725 cores based on an "all-big-core design" that relies entirely on performance cores. One ARM Cortex-A725 core operates at 3.25 GHz, three others at 3.0 GHz, while the remaining four cores serve as energy-efficient performance cores and run at up to 2.1 GHz.
At the same time, the ARM cores rely on different amounts of L2 cache memory: 1 core with 1 MB, 3 cores with 512 KB and 4 cores with 256 KB. LPDDR5x-8533 RAM can be used as RAM and UFS 4.0 is supported as internal memory.
Compared to its predecessor, the MediaTek Dimensity 8300, the MediaTek Dimensity 8400 and therefore the 8450 is said to achieve up to 41 percent higher multi-core performance, while the ARM Mali-G720 MC7 graphics unit runs up to 24 percent faster than the ARM Mali-G615 MC6 of its predecessor. According to the manufacturer, the energy efficiency of the CPU and GPU has also improved, with 44% and 42% lower power consumption respectively. The MediaTek NPU 880 is used as the AI chip.
In terms of connectivity, dual 5G with a theoretical peak download speed of up to 5.17 GBit/s is available, as well as WiFi 6E and Bluetooth 5.4. Video recording is supported with up to 4K at 60 fps.
The integrated ARM Mali-G720 MC7 graphics unit can control displays with a resolution of up to 2,960 x 1,440 pixels (WQHD+) and a refresh rate of up to 144 Hz.
